Application January 10, 1955, Serial No. 480,789

3 Claims. (Cl. 200-131) This invention relates to a fuse holder which has for its primary object the elimination of the many parts and assembly work required in the construction of conventional fuse holders.

A further object of the invention resides in the provision of a fuse holder which will permit the ready replacement of a fuse wire or strip of the desired amperage.

The construction of this invention features recesses for lockingly holding contact terminals in engagement with a fuse strip or wire within a transparent fuse holder formed from a pair of generally semi-cylindrical holder sections. The contact terminals are provided with novel anchor means for holding the contact terminals in position and in engagement with the fuse wire or strip. Resilient bands which may be of a suitable and selective material embrace and hold the holder sections together.

A further object of the invention resides in the provision of a fuse holder employing means for preventing end and side slip of the holding sections while also preventing external fuse flash.

Still further objects and features of this invention reside in the provision of a fuse holder that is simple in construction, highly eicient in operation, and inexpensive to manufacture thereby permitting Wide distribution and utilization.

These, together with the various ancillary objects and features of the invention which will become apparent as the following ydescription proceeds, are attained by this fuse holder a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure l is a perspective View of the fuse holder comprising the present invention;

Figure 2 is an enlarged longitudinal sectional view as taken along the plane of line 2-2 of Figure l;

Figure 3 is an enlarged vertical sectional View as taken along the plane of line 3-3 in Figure l;

Figure 4 is an enlarged plan view of one of the holder sections;

Figure 5 is a plan View on an enlarged scale of another holder section;

Figure 6 is a perspective view of one of the contact terminals.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates the fuse holder comprising the present invention. This fuse holdei is constructed from a pair of holder sections 12 and 14 each of which are formed by molding or other suitable means from a preferably transparent insulative material.

The holder sections 12 and 14 have complementary bores 16 and 18 therein which cooperate to form a centrally longitudinally extending bore. The complementary bores 16 and 18 terminate at recesses 20, 22 and 24, 26 respectively for reception of contact terminals 28 and 30 to which leads 32 and 34 are attached, the leads being e 2,759,065 Ice Patented Aug. 14, 1956 embedded as at 36 and 38 in the contact terminals 28 and 30. The recesses 20, 22, 24 and 26 have conical portions 40, 42, 44 and 46 for reception of the truncated conical anchors 48 and 50 which are outwardly wider than the bores 16 and 18 to lockingly position the contact terminals 28 and 30 in the respective recesses. Secured to the anchors 48 and 50 are reduced neck portions 52 and 54 to which are connected the enlarged portions 56 and 58 of the contact terminals 28 and 30.

Positioned within the bore formed by the complementary bores 16 and 18 is the fuse wire or a strip 60 of desired amperage Which has bent end portions 62 and 64 which extend into the recesses and engage the truncated conical anchors 48 and 50 to complete an operative electrical circuit therebetween.

The holder sections 12 and 14 are provided with grooves 66 and 72 therein into which tongues 68 and 70 integrally formed with the holder sections are adapted to extend. The tongues and grooves terminate short of the ends of the holder sections thereby preventing end and side slip while also serving to form a baille for preventing external fuse Hash.

Positioned about and embracing the holder sections 12 and 14 so as to hold the holder sections 12 and 14 together are bands 74 and 76 of elastic and resilient material such as rubber or the like. It is possible to easily replace the fuse strip or wire 60 by merely removing the terminals, spreading the halves of the holder against the resilent bands 74 and 76 and then removing the old fuse strip and inserting a new fuse strip.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A fuse holder comprising a pair of substantially semi-cylindrical holder sections of electrically insulative material, said holder sections having complementary bores extending therethrough and terminating in complementary recesses at the ends of said holder sections, contact terminals received in said recesses, a replacable fuse strip in said bore extending between said recesses and engaging said Contact terminals, and resilient collars embracing said holder sections holding said holder sections together, said holder sections having complementary tongues and grooves arranged on opposite sides of said bores.

2. A fuse holder comprising a pair of substantially semi-cylin-drical holder sections of electrically insulative material, said holder sections having complementary bores extending therethrough and terminating in complementary recesses at the ends of said holder sections, contact terminals received in said recesses, a replaceable fuse strip in said bore extending between said recesses and engaging said contact terminals, and resilient collars embracing said holder sections holding said holder sections together, said holder sections having complementary tongues and grooves arranged on opposite sides of said bores, each of said contact members having a substantially truncated conical anchor lockingly engaged in said recesses.

3. A fuse holder comprising a pair of substantially semi-cylindrical holder sections of electrically insulative material, said holder sections having complementary bores exten-ding therethrough and terminating in complemen tary recesses at the ends of said holder sections, contact terminals received in said recesses, a replaceable fuse References Cited in the file of this patent UNITED STATES PATENTS Goldman et al July 7, 1914 Hawkins July 14, 1925 Roth Mar. 20, 1928 Smith Sept. 12, 1933 FOREIGN PATENTS France Oct. 17, 1950
